BOTTLE-STOPPERV Application filed May 7,. 1919. Serial No. 295,335.

0 all whom it may concern:

Be it known that I, J GEN PA'rRoNnLL, a citizen of the United States, residing at Orange, in the county of Orange and State of Texas, have invented new and useful Im provements in Bottle-Stoppers, of which the following is a specification.

This invention relates to bottle stoppers,

having for its primary object to provide a I tion plugs.

A further object of the invention is to provide a stopper of the character stated which may be easily and quickly constructed, which is of simple construction and which may be manufactured at extremely low cost, which is easily applied to and removed from the container,which is constructed in such manner as to minimize the liability of breakage or derangement, and which is equipped with improved means whereby the stopper may be frictionally bound with the inner walls of the bottle or jug neck after having been applied thereto. I I

, With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawing, and

particularly pointed out in the claims.

In the drawing A v Figure 1 is a fragmentary sectional View taken through the upper portion of a conventional form of bottle, andillustrating the application of a stopper constructed in accordance with the invention,

Fig. 2 is an enlarged transverse sectional view taken substantially upon line 2-2 of Fig. 1, V

Fig. 3 is a detail perspective view of one of the stopper sections,

Fig. 4 is a sectional view taken through the section illustrated in Fig. 3,

Fig. 5 is a perspective view of the outer section of the stopper, and

Fig. 6 is a transverse sectional View taken through the lower portion of the said outer section.

In carrying out the invention, the' stopper is formed of a pair of interfitting sections, each formed of thin pliable ineX ensive metal and each section is capable o..- rotat ing independently of the other. These sec tions are held together by improved means, whereby accidental disengagement of the sections from each other is prohibited, and yet the said sections maybe freely moved so as to firmly clamp the stopper within the bottle neck by the means of the instrumentality to be hereafter detailed. It is preferred thatthe'metal'ernployed in making up the stopper be of thin tin or other metallic composition, so treated as to obviate the possibility of corrosion or ill efiect upon the contents of the container.

, Referring now particularly to the drawing, 7 indicates the bottle neck of conventional form, and 8 is the improved stopper. The stopper comprises inner and outer sections 9 and 10, the latter being cup-shaped and of such size as to snugly fit one within the other. The inner section 9 is provided ,near its upper end with an annular bead 11,.

over which an outwardly extending annulus 112 on section lO engages. This annulus may be crimped upon the bead if desired, but it is not engaged with sufiicient friction to prevent rotation of the sections independently of each other. 1

The section 9 is provided near its lower end with relativelyshort and narrow indentations .13 extending circumferentially of the section, and the section 10 is similarly formed with depressions 14:. These depressions may be formed in the sections after the latter have'been assembled, so that the said depressions will be in registration with each other. As the metal of which the sec- 1 tions are formed is thin and pliable, rotary movement of the section 9 will cause the depressed portions 14 of the outer section 10 to move outwardly and into frictional engagement with the wall of the bottle neck.

. This action causes the stopper to be securely fastened within the bottle neck and materially assists in hermetically sealing the bottle.

The lower end of the outer section 10 is provided with a cap of impervious or paraflin paper 15, and as the edges of this cap extend around the edges of the stopper section, the same will be firmly engaged between the stopper and the wall of the bottle neck when the stopper has been applied. The turning movement of section 9 within section 10 will cause the thin metal of the last named section to firmly bind against the tion 10 will also tend to firmly bind the edge of the bottle cap 15 against the bottle neck walls.

From the foregoing it is obvious that I have provided a bottle stopper of simple construction and which will efficiently perform the functions set forth. By reason of the fact that the metal constituting the sec tions is of light weight and easily deflected, the sealing process may be carried out without the use of special skill or tools. Slight rotary movement applied to the inner section 9 with the fingers will be sufficient to cause the outer section to be forced into frictional engagement with the bottle neck walls. After the stopper has been applied, the possibility for leakage around the sides of the stopper are obviated. The stopper may be easily withdrawn in the usual manner, or the inner section may be rotated rearwardly so as to bring the depressions therein in alinement with the corresponding depressions in section 10 before extracting pressure is applied. It may be found desirable to construct the inner section of the stopper of material of somewhat heavier character than the material of the outer section, whereby distortion of the inner section will be eliminated.

WVhile the above is a description of the preferred embodiment of the invention, it is obvious that the invention is not necessarily restricted thereto, as changes in the minor details of construction may be resorted to without departing from the invention as defined in the claims.

Having thus fully described my inven tion, I claim l. A bottle stopper comprising a body formed of interfitting sections, the said sec tions being rotatable independent of each other, and interfitting depressed portions in the sides of said sections.

2. A bottle stopper comprising a body formed of interfitting circumferentially continuous cup-shaped sections of thin pliable material, said sections being rotatable independently of each other, interfitting depressed portions in the sides of said sections operative on rotation of one of said sections for bulging and clamping the other section in a bottle neck, and a diaphragm separate from and covering the lower end of the outer section.

3. A bottle stopper comprising a body formed of interfitting sections of pliable material, the said sections being capable of rotating independently of each other, and the said sections being provided in. their sides with interfitting depressed portions.

l. A bottle stopper comprising a body formed of hollow interlitting independently rotatable sections formed of pliable material, an annular bead on one of said sections, an annulus on the other section engaging over said bead, and interfitting depressed portions on said sections near the lower ends thereof operative on rotation of one of said sections for expanding and clamping the other section in a bottle neck.

5. A bottle stopper comprising a body formed of hollow inter-fitting circumferentially continuous cup-shaped sections of thin pliable material capable of rotating independently of each other, ooacting surfaces on said sections operative by the rotation of the inner section for causing the outer section to bulge, and a cap formed of impervious material secured over the lower end of the outer section and engaging around the sides of the said section.

6. A bottle stopper comprising a body formed of interfitting sections, the outermost of said sections being formed of pliable material, the said body being round in cross section to fit within the neck of a bottle, and circumferential depressed portions in the said inner and outer sections, said depressed portions being of short duration whereby rotation of the inner section will caus its depressed portions to move out of alinement with the corresponding portions of the outer section whereby the latter will be pressed outwardly against the sides of the bottle neck.

In testimony whereof I affix my signature.

JOHN PATRONELL.
